LEATHER-RQUGHEN ING v MACHINE.y

Application filed January To all whom t may concern:

Be it known that I, WILLIAM F. HORST- ING, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, .have invented certain new and useful Improvements in a Leather-Roughening Machine; and I hereby declare that the following is a full, clear, and exact description `of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This inventionrelates to a leather roughening machine constructed to permit strips of leather, sheets of leather orl stretched butt bends to be fed through themachine beneath a brush device adapted to act on one surface of each strip of leather to roughen the same so that glue applied thereto will have; agripping surface when strips of leather arev glued together to afford several thicknesses of leather `from which belts and thelike may be cut.

Y It is an object of this invention to provide a machine adapted to roughen a surface of a strip of leather fed through the machine. Itis an important object of the invention toprovide ka machine having feeding means adapted to feed a strip of leather through the machine against the action of a wire brush which acts on thestrip of leather to roughen one surface thereof so that glue will readily adhere thereto when it is desired to glue several layers of leather together. Y Other and further important objects of this invention will be apparent from the disclosures in the specification and the ac,- companying drawings.

- This invention (in a preferred form) is illustrated in the drawings andl hereinafter more Vfully described.

rOn the drawings:

Figure 1 is a side elevation of a leather' roughening machine embodying the principles of this invention.

Figure 2 is a fragment-ary rear view of the machine.`

Figure 3 is a top plan view of the machine with parts broken away. Y Figure 4 is a fragmentary front elevation ofthe machine.A

Figure 5 is a transverse vertical section taken on line 5-5 of Figure 1.

5, 1,924.' serial No. $34,494:.v

Mounted on one projecting end ofthe driv ing shaft 4 is a fixed pulley 6 and a loose `pulley 7 disposed adjacent one another and adapted to receive a drive by means of av belt connected with any suitable source of supply such as a motor or the like. I

Fixed on the opposite end of the driving shaft 4- is a gear or pinion 8 having a small sprocket 9 secured on the shaft 4 to the out side of the gear 8. A chain 10is engaged around the sprocket 9 and around alarger sprocket 11 mounted on one end of a transverse shaft 12. The shaft 12 is journalled transversely beneath'the table 1 in suitable bearings. lMounted on the shaft 12 below an opening 13 in the table 1 is a lower rubber covered feed roller 14 which c oacts with an upper rubber covered feed roller 15. The upper feed roller 15 is secured on a transverse` shaft 16 journalled in bearings V17 formed on a pair of side arms 18 which are pivotedly-mounted on the upper rear shaft 5. Mounted on one end of the shaft 16 is a sprocket 19 around which aV chain 2() is trained. The chain 2On is also engaged around a smallersprocket 21 secured on one end ofthe upper rear shaft 5 to the outside of a gear 22. The gear 22 is fixed on the shaft 5 and is in mesh with the gear 8 to receive a drive therefrom.

A cross bar 23 connectsthe forward ends of the arms 18 and is provided with end bearing members 24 having end plates 25 which slidably fit within guide members 27 formed on the ends of the arms 18. Adjusting screws 26 are supported on the guide members 27 and engage the plates 25 of the cross bar 23 to permit the cross bar to be adjusted. Journalled in the bearings 24 is a shaft 28 having a plurality of spaced disks 29 mounted thereon. Each of the disks 29 has a plurality of feed pins 30 mounted radially on the periphery thereof. Secured on one end of the shaft 28 is a sprocket vwheel 31 around which a chain 32 is engaged, The chain 32 is also engaged around a sprocket wheel 33 mounted on one end of the shaft 16.

Connected to the arms 18, is a brush back 34 provided with metal or wire brush bristles 35. Supported on the arms 18 to the outside of the brush 34 is a rubber covered upper feed roll y41v adapted to co-act with a lower rubber covered feed roll 42 supported on the table 1.A rlhe upper feed roll 41 is driven by means of a chain 43 and suitable sprockets from-the shaft 16 while the lower feed rollv 42 is driven by a chain 44 and suitable sprockets from the lower shaft 12.

Secured to the ends of the cross bar 23 are the upper ends of a pair of bent rods 36 the lower ends of which are fastened to a control lever 37 which is pivotedl intermediate its ends on a stand 38 adapted to rest on the floor. he forward end of the lever 37 has a foot plate 39 secured thereon, while the rear end of the lever 37 has a counterweight 40 mounted thereon.

rllhe operation is as follows:-

Vlhen it is desired to roughen one surface of a strip of leather or a stretched butt bend oneend of the strip of leather is laid on the front end of the table 1 beneath the pin roller or primary feed roller 29-30 which normally is held in an elevated position due to the action of the counter-weight 40 which acts to hold the outer end of the lever 37 elevated thereby causing the rods 36 to hold the cross bar 23 and the arms 18 in a raised position. The upper feed rollers 15 and 41 are thus also elevated out of contact with the respective lower feed roller 14 and 42.

With one end of the strip of leather in position beneath the pin roller 29-30 the machine is started by shifting the driving belt from the loose pulley 7 onto the drive pulley 6 thereby causing rotation of the shaft 4 and the lower rollers 14 and 42 through the respective chains 10 and 44. rlhe gear 22 being in mesh with the gear 8 acts to cause rotation of the shaft 5 and the upper feed rollers 15 and 41 through the respective chains 20 and 43. rlhe pin roller 22)--30v is operated by the chain 32 from the sprocket-wheel 33 on the shaft 16.

lVith the advance end of a strip of leather positioned on the table beneath the pin roller the operator steps on the foot plate 39 thereby lowering the outer end of the lever 37 and raising the inner counter-weighted end thereof. As the outer end of the lever 37 is lowered the rods 36 act to pull the pivoted frame 18-23 downwardly about the shaft 5. The pin roller 29 30, the brush 35 and the upper feed rollers 15 and 41 are all lowered into operating` positions. When this occurs the pins 30 on the pin roller engage the strip of leather and act to feed the strip of leather inwardly over the table 1 between the first set of feed rolls 41 and 42 and beneath the wire-brush. The wire bristles 35 of thel lowered brush scrape the upper surface of the strip ,of leather and roughen said surface. VY'Vith the continued advance ofthe strip of leather the forward edge of said strip passes between'the second set of feed rollers 14 and 16 and is fed rearwardly through the machine over the table 1` The roughening` of the-surface of the leather may be regulated'by the amount of pressure applied to the foot plate 39.

After a strip of leather has been roughened the lever 37 is released thereby allowing the counter-weight 40 to drop by gravity to swing the outer end of the lever up- .vardly. The rods 36 thus cause the pivoted frame 18-23 to swing upwardly away from the table 1 into normal position to permit the next strip of leather to be inserted into the machine. I

l am aware that many changes may be made, and numerous details of construct-ion may be varied through a wide range without departing from the principles of this invention, and 1 therefore do .not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.
